Preeminent role of the Van Hove singularity in the strong-coupling analysis of scanning tunneling spectroscopy for two-dimensional cuprates
Giorgio Levy de Castro, Christophe Berthod, Alexandre Piriou +2
In two dimensions the non-interacting density of states displays a Van Hove singularity (VHS) which introduces an intrinsic electron-hole asymmetry, absent in three dimensions. We…

Charge carrier interaction with a purely electronic collective mode: Plasmarons and the infrared response of elemental bismuth
Riccardo Tediosi, N. P. Armitage, E. Giannini +1
We present a detailed optical study of single crystal bismuth using infrared reflectivity and ellipsometry. Colossal changes in the plasmon frequency are observed as a function of…
